- Spark plug wrench
- New spark plugs (correct type for your Skoda Fabia)
- Spark plug gap tool
- Dielectric grease
- Flashlight
Procedure:
1. Turn off the engine and allow it to cool down. It's important to work on the spark plugs when the engine is cool to avoid burns.
2. Open the hood of the car. Locate the hood release lever inside the car, usually near the driver's footwell. Pull the lever and lift the hood to access the engine bay.
3. Locate the spark plugs. On the Skoda Fabia, the spark plugs are located on the top of the engine, arranged in a row. They have black or dark gray rubber caps over them.
4. Remove the spark plug caps. Gently pull the caps straight up to remove them. Be careful not to drop the caps into the engine bay.
5. Use a spark plug wrench to loosen and remove the old spark plugs. Place the spark plug wrench over the spark plug and turn it counterclockwise to loosen it. Be careful not to drop the spark plugs into the engine bay.
6. Check the gap on the new spark plugs. The gap is a small distance between the center electrode and the ground electrode on the spark plug. It should be set according to the specifications provided in your car's owner's manual. Use a spark plug gap tool to adjust the gap if necessary.
7. Apply a small amount of dielectric grease to the threads of the new spark plugs. This will help prevent the spark plugs from seizing in place and make future removals easier.
8. Screw the new spark plugs into place by hand. Turn them clockwise until they are snug.
9. Use the spark plug wrench to tighten the new spark plugs. Tighten them until they are snug, but do not overtighten them.
10. Replace the spark plug caps. Push them down firmly until they are seated properly.
11. Close the hood of the car.
Tips:
- If you have trouble removing the spark plug caps, you can try using a pair of pliers. Gently pry the caps off using the pliers, being careful not to damage them.
- Be careful not to drop the spark plugs or spark plug caps into the engine bay. If they do fall in, you will need to retrieve them before starting the engine.
- It's a good idea to replace all four spark plugs at the same time, even if only one is bad. This will help ensure that all spark plugs are performing at their best.
- If you are uncomfortable performing this task, you can always have it done by a qualified mechanic.
